Question

Rohan buys an old washing machine for rs 5500 and spends rs 1000 on its repairs if he sells the scooter for rs 7800 find his gain percentage?​

Answer 1

The gain percentage is 20%.

Step-by-step explanation:

Cost price of scooter = Rs. 5500

Rohan spends on its repairs = Rs. 1000

Total cost price of scooter = C.P = Rs. 5500 + Rs. 1000 = Rs. 6500

Selling price of scooter = S.P = Rs. 7800

Gain = $\frac{S.P - C.P}{C.P} \times 100$

=> Gain = $\frac{7800-6500}{6500}\times 100$

=> Gain = 20%

Hence, the gain percentage is 20%.
